1. Field of the Invention
The present invention relates to a connector, and particularly to an electrical connector capable of receiving two electronic cards.
2. The Related Art
With the ever-increasing miniaturization and multifunction of portable electronic devices, such as mobile phones, digital video cameras and the like, it is necessary to insert different types of electronic cards into the portable electronic device for data processing, identifying function and so on, and to reduce the occupied space in the portable electronic device. Therefore, an electrical connector presently disclosed, which allows inserting two electronic cards thereinto at a time for meeting the present demand.
For instance, related U.S. application Ser. No. 10/721,202, filed Nov. 25, 2003, entitled “Electrical Connector Adapted For Use With First And Second Electronic Cards”, which is incorporated herein by reference, presents an electrical connector structure that can receive the first electronic card inserted into a first card receiving space and the second electronic card inserted into a second card receiving space. However, such structure is not convenient to insert the electronic cards thereinto, because an insertion opening of the first card receiving space is adjacent to that of the second card receiving space. Furthermore, once the first electronic card or the second electronic card cannot connect with the electrical connector functionally, the electrical connector will be entirely replaced, which reduces the usage life of the electrical connector.
Accordingly, an object of the present invention is to provide an electrical connector which has two separately removable elements for accommodating a first electronic card and a second electronic card. The electrical connector has a first connector element that includes a first base having a first body, and a set of first terminals received in the first base. Two lateral walls and two holding walls extending upwards and downwards from two opposite sides of the first body to form a first receiving space and a receiving chamber therebetween respectively. The first receiving space, with a first insertion opening defined, is adapted for receiving the first electronic card. A second connector element removably received in the receiving chamber includes a second base, a set of second terminals mounted in the second base and a second shell. The second shell is engaged with the second base to form a second receiving space, with a second insertion opening defined opposite to the first insertion opening, for receiving the second electronic card.
As described above, the second connector element is removably received in the receiving chamber of the first connector element, which is not only capable of receiving the first and second electronic cards, but also reduces occupied horizontal space of the electrical connector. Meanwhile, the first connector element or the second connector element can be alternatively exchanged when either the first connector element or the second connector element has a breakdown, which prolongs the usage life and reduces the manufacturing cost of the electrical connector. In addition, the first insertion opening disposed opposite to the second insertion opening benefits for convenient insertion of the electronic cards.
The present invention will be apparent to those skilled in the art by reading the following description of an embodiment thereof, with reference to the attached drawings, in which:
With reference to
Please refer to
The short terminal 122 has a second fixing portion 1221 of substantially rectangular shape. One end of the second fixing portion 1221 is extended downwards to form a second soldering portion 1222 which is narrower than the second fixing portion 1221 and soldered on the PCB, while the other end of the second fixing portion 1221 is bent obliquely and upwards, and then curved downwardly to form a second contacting portion 1224 similar to the first contacting portion 1215 for connecting with the first electronic card C1. Two sides of the second fixing portion 1221 protrudes oppositely to form a second buckling portion 1223 adjacent to the second soldering portion 1222, respectively, for engaging with the first buckling recess 117.
Please refer to
The second terminal 22 includes a fixing portion 221, a soldering portion 222 and a contacting portion 223. The fixing portion 221 is a flat-plate shape and accommodated in the first cavity 214 a, with two opposite sides thereof restrained in the corresponding buckling cavities 215. The soldering portion 222 is extended downwardly from a front end of the fixing portion 221 for being soldered on the PCB. The contacting portion 223 extended backwards from a rear end of the fixing portion 221 is narrower than the fixing portion 221 and received in the second cavity 214 b, a distal end thereof formed an arc shape to exceed a top surface of the second body 211 for electrically connecting with the second electronic card C2.
The second shell 23 includes a second covering plate 231 and three second lateral plates 232 extending downwardly from three contiguous edges of the second covering plate 231. The second lateral plates 232 respectively have a fixing hole 2321 corresponding to the fixing protrusion 219 for fixing the second shell 23 to the second base 21. A bottom of the second lateral plate 232 extends downwards to form a plurality of buckling tabs 2322 bent inwards to button a bottom surface of the second base 21 in assembly. The second shell 23 is coupled with the second base 21 to form a second receiving space 25, with a second insertion opening 251 defined at a front end of the electrical connector 1, for receiving the second electronic card C2.
The ejection mechanism 24 mounted in the second base 21 includes a leading rod 241, a sliding member 242 and a spring 243. The leading rod 241 is received in the heart-shaped recess 216, the sliding member 242 is mounted in the sliding recess 217, and the spring 243 is disposed elastically between the sliding member 242 and the positioning portion 218. The positioning portion 218 is inserted into an end of the spring 243 for preventing the spring 243 from moving.
Please refer to
As described above, the second connector element 20 is removably received in the receiving chamber 15 of the first connector element 10, which is not only capable of receiving the first and second electronic card C1 and C2, but also reduces occupied horizontal space of the electrical connector 1. Meanwhile, the first connector element 10 or the second connector element 20 can be alternatively exchanged when either the first connector element 10 or the second connector element 20 has a breakdown, which prolongs the usage life and reduces the manufacturing cost of the electrical connector 1. In addition, since the placed direction of the first and second soldering portions 1212, 1222 of the first terminal 12 is opposite to that of the soldering portion 222 of the second terminal 22, the first terminal 12 and the second terminal 22 are soldered on the PCB, respectively and separately, which can simplify welding process.
The foregoing description of the present invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. Such modifications and variations that may be apparent to those skilled in the art are intended to be included within the scope of this invention as defined by the accompanying claims.
